TROUBLESHOOTING
DEMOJM Is Undetected
Development Packages include in-circuit debugging software, flash
programming software, a Windows IDE, and register file editor.
Q: The connection assistant indicates that my DEMOJM is undetected even
though I have connected the hardware to my USB port. What should I do?
A: The connection assistant, which displays in either Codewarrior or P&E’s
development software, is a dialog which allows the user to connect to the
DEMOJM hardware. If this dialog indicates that the DEMOJM hardware is not
connected to the PC, the first step is to make sure that the DEMOJM
hardware is connected to the PC via a USB 2.0 high-speed cable. If it is
connected, unplug and then plug in the USB cable on the DEMOJM board
and click refresh in the connection assistant. If the hardware still does not
show up, try the following remedies:
(A) Re-Enable the USB driver
If you connected the DEMOJM interface prior to the installation of P&E’s
Embedded Multilink drivers, Windows will not have been able to find the
appropriate driver and may have disabled the device. The DEMOJM board
shows up in Window’s device manager as a “P&E Multilink,” since it contains
P&E’s Embedded Multilink circuitry. If you unplug and then plug in the device,
Windows will automatically disable it even if you have installed the drivers. To
force windows to try to load the driver again, perform the following steps while
the DEMOJM interface is connected to the computer:
(B) Re-Install the USB driver
1. Open the Control Panel (Start Button->Settings->Control Panel)
2. Double Click the "System" Icon
3. Select the "Hardware" tab
4. Click the "Device Manager" Button
5. The "P&E Multilink" device will be shown with an exclamation mark
6. Click the "Reinstall Driver…" button and follow the dialog instructions
next to it. Double-click this device.
to have Windows automatically install the driver.
